Floatation of Buried Submarine Pipeline under Cyclic Loading of Water Pressure -Numerical and Experimental Studies- [PDF]

open access: yes, 2000
A dynamic response of a submarine pipeline buried in sandy seabed sediments to water loading generated by harmonically oscillating water-table vertical movements is examined in the present report experimentally and numerically.

Fatigue crack propagation model of concrete under water pressure based on energy approach

open access: yesShuili Shuiyun Gongcheng Xuebao, 2020
For the coupled action of low frequency fatigue loading and pore water pressure, the energy for fatigue crack growth of concrete is usually divided into two aspects.

Pore water pressure change-related characteristic and its critical rupture precursor of rock under triaxial compression

open access: yes工程科学学报, 2015
The change of pore water pressure in saturated rocks was closely associated with its damage deformation. In order to study the precursory characteristics of pore water pressure before the damage of saturated rock, the triaxial compression test and ...

Some experience in measuring pore water suction in Dublin glacial till [PDF]

open access: yes, 2004
Several recent articles and discussions in GIN, by Penman (2002), Thomann et al. (2003), Ridley (2003) and Sellers et al. (2003) highlight the importance of pore water pressure and suctions and in particular the difficulties associated with measuring ...

Seamless pressure-deficient water distribution system model [PDF]

open access: yes, 2010
Pressure-deficient conditions are a common occurrence in water distribution systems. These situations require accurate modelling for timely decision making.

Effects of Initial Shear Stress and Vibration Frequency on the Dynamic Pore-Water Pressure of Saturated Sands

open access: yesAdvances in Civil Engineering, 2018
The cyclic triaxial system is used to investigate the effects of confining pressure, initial shear stress, vibration frequency, and dynamic stress on the pore-water pressure characteristics of saturated sand in the Wenchuan area.

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]

open access: yes, 2009
Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in

Bench-Scale Experiments on Effects of Pipe Flow and Entrapped Air in Soil Layer on Hillslope Landslides

open access: yesGeosciences, 2019
Soil pipes are commonly found in landslide scarps, and it has been suggested that build-up of pore water pressure due to clogged soil pipes influences landslide initiation.

Excess pore water pressure generation in fine granular materials under undrained cyclic triaxial loading

open access: yesInternational Journal of Geo-Engineering, 2023
Understanding the mechanism of excess pore water pressure generation in subgrades is essential for not only designing but also further maintenance purposes.

Numerical investigation of solute migration and release from sediments driven by wave-induced accumulation of pore water pressure

open access: yes, 2023
Sediments with poor drainage conditions are prone to build-up of excess pore water pressure when exposed to dynamic wave loading. This results in accumulated seepage flow that may have a significant impact on migration of solutes in marine sediments.
